• Resistance is increasing rapidly
• Resistance is a high priority with US and EU authorities
• Even Colistin, invented in the fifties and abandoned in the sixties due to neuroand nephrotoxicity, is increasingly used but resistance is growing
ANTIMICROBIAL PEPTIDES WITH NOVEL MODE OF ACTION
Bacterial Resistance An escalating problem calling for new MoA antibiotics
Carbapenem resistant enterobacteria
4
• Most potent anti Gram-negative AMP identified by Novozymes
through screening effort comprising more than 500 organisms
• Arenicin-3 is a 21 AA peptide from the lugworm Arenicola marina
• New and dual MoA
• Novozymes has tested ≈ 250.000 Arenicin variants
• Adenium has subjected the 10 best to extensive characterization/
lead optimization and selected AA139 as the clinical candidate
• GMP manufacture initiated October 2013

Arenicin has a completely novel MoA:
Distortion of phospholipid synthesis by
interaction with MlaC
Arenicin also inhibits protein synthesis
through inhibition of cytosolic processes
MlaC is a periplasmic binding protein
maintaining phospholipid homeostasis

External activities and cost for development of AA139 in cUTI
16
• The Arenicin platform provides opportunities for multiple
clinical indications:
• AA139 in other clinical indications than cUTI
(e.g. HAP/VAP, IAI)
• Other Arenicin variants for selected pathogens
(i.e. variants with high activity against e.g. MDR N.
Gonorrhoeae identified)
• Adenium is acquiring an additional AMP platform from
Novozymes. AP114 has high activity against C. difficile
• cGMP material AP114 available
• AP114 program targeting C. difficile infection currently
being developed
• FIM studies possible in H2-2014

Additional programs target other GAIN pathogens

Development cost of USD 6 mio for AA139 through phase I
Development cost of USD 2 mio for AP114 through phase I
G&A cost of USD 2 mio
Company plans to raise a minimum of USD 10 mio in a
series A round in H1 2014
• Current investors (Sunstone Capital and Novo) will
participate in the series A round
• Plan to attract 1 – 2 additional investors to the syndicate

Plans for series A round
19
• AA139, one of very few new MoA, broad spectrum MDR
Gram-negative
• First in class antibiotic with strong patenting through 2033
• Increasing resistance problem spurs interest in new antiinfectives
• Regulatory guidelines (e.g. GAIN act) provides additional
incentives for anti-infective development
• Recent deal activity (e.g. Cubist – Trius/Optimer) confirms
interest in antibiotics
• Additional opportunities for AA139 in other indications
• AP114 program targets C. diff infection, a growing problem
with rapidly aging populations and a GAIN pathogen
